A software program used on the Mars Pathfinder mission has
been named winner of the 1997 NASA Software of the Year Award,
the agency's Inventions and Contributions Board has announced.

Drs. Abhinandan Jain, Guillermo Rodriguez and Guy K. Man of
NASA's Jet Propulsion Laboratory developed the software called
Dynamics Algorithms for Real-Time Simulation (DARTS). The DARTS
software can be used to generate real-time simulations to test
and verify flight software and hardware for a variety of
spacecraft missions.

The software uses a new form of mathematics, known as
spatial operator algebra, that NASA engineers calculate has been
responsible for phenomenal improvements in simulation speed and
fidelity of up to 10 million times. The team received an award
for development of the new algebra three years ago. In addition
to Mars Pathfinder, this software has been used on JPL's Cassini,
Galileo, Stardust, New Millennium and proposed Neptune Orbiter
missions.

The award announcement was made by Frederick D. Gregory,
NASA's associate administrator for safety and mission assurance,
and Dr. Daniel R. Mulville, NASA chief engineer and chair of the
agency's Inventions and Contributions Board.

The winning software has saved over $10 million to date on
NASA missions. NASA will present the award at the Technology
2007 Conference to be held in Boston, MA, on September 23.
